RAPID PROTOTYPING PROCESS ALLOWING THE USE OF PASTY MATERIALS, AND DEVICE FOR IMPLEMENTING SAME

摘要

The invention concerns a fast three-dimensional modelling method comprising the following steps: a phase which consists in transforming the raw material in the work space (32) by means of a device inducing transformation (1); at least at one moment, a phase which consists in supplying non transformed material, downstream of the doctor blade; a phase which consists in covering the transformed material (PI) with non-transformed material (MAT), which consists in moving the blade in a direction (F), driving in rotation about an axis a rolling member (26, 27) whereon an extruded log of non-transformed raw material (28) is wound, arranging a pushing member (22) such that its proximal edge (23) coincides with the surface of said work space, and positioning said rolling member downstream of the pushing member, and opposite thereof, so as to channel the extruded log of non-transformed material towards a cavity formed between the proximal edge and the rolling member facing it.
